The limitation of human knowledge, when trying to comprehend the Supreme Being is
brought out in the above epigram.
Not by reasoning but only by an awakening
can we get a vision of the Supreme Spirit. Life, in relation to the Ultimate Reality, is
like a state of sleep. Reason, in respect of Ultimate Reality, is like the impossible
conception of a sleeping man trying to know what he is about, without waking up. As sleep
is to waking, so is ordinary life to the state of realization.
Self-discipline gives strength of spirit:
To one so strengthened, knowledge gives immortality:
The Self is itself immortal, and one has
but to know it to become immortal.
